Technology plays an important role in people’s day-to-day life and various aspects of life  including education also use technology. Artificial Intelligence is regarded as an example of the advancement of technology. The purpose of this study is to investigate students’ perceptions of using Artificial Intelligence mobile applications to improve English listening skills. It was under phenomenological qualitative research characterized by an interdisciplinary approach, mainly education and technology. The online interview was used to gain information from students’ on the specific theme of artificial intelligence mobile applications in improving English listening skills. The survey consists of seven questions which become category such as 1. The Knowledge of Artificial Intelligence; 2. The Knowledge of Tune In, Joox Music, VOA Learning English Listening every day, and Netflix; 3. The Use of the Applications; 4. The Reason to Use the Applications; 5. The Use of Applications in Improving English listening Skills; 6. The Influence of the Applications toward The Users; 7. The Most Effective and Efficient Applications to Improve English Listening Skills. This survey was conducted at the Faculty of Psychology in Universitas Sarjanawiyata took part in this study. Participants were three females and two males. The results showed that the most effective and efficient Artificial Intelligence mobile application to improve English listening skills is Netflix.

Nowadays the classroom management is very important for the teacher. In Indonesia, the class had several categories. Namely, international class and regular class. The teacher need to be aware of this phenomenon. They should established some strategies in order to manage their class. The population in Indonesian school nowadays was various. There are small and large classes. On this research, the researchers would like to know what kind of strategies that the teacher used in managing the large class. On this research, the researcher used Qualitative approach in the form of Descriptive qualitative design. The result found that there are many strategies that the teacher can use in managing the large class.

Pinang (Areca catechu L) secara tradisional dimanfaatkan untuk mengobati luka dan pendarahan, infeksi saluran kemih, sakit kaki dan kecacingan. Studi penelitian modern, pinang memiliki efek farmakologis sebagai antijamur. Penelitian ini bertujuan untuk mengetahui kemampuan ekstrak etanol biji pinang terhadap pertumbuhan jamur Candida albicans. Penelitian ini merupakan penelitian eksperimen. Langkah-langkah yang dilakukan dalam penelitian ini, mula-mula biji pinang yang telah dikupas dijemur selama 7-10 hari. Setelah kering, dihaluskan menjadi serbuk. Selanjutnya proses ekstraksi fitokimia menggunakan metode maserasi menggunakan etanol. Perolehan ekstrak dilakukan menggunakan rotary vacuum evaporator. Ekstrak yang diperoleh dibuat taraf konsentrasi 20, 40, 60 dan 80 g/ml. Masing-masing taraf konsentrasi dilakukan uji daya hambat anti jamur menggunakan metode Kirby Bauer. Zona bening yang terbentuk diukur menggunakan jangka sorong. Data dianalisis menggunakan statistik non Parametrik Kruskal Wallis dan uji lanjut Mann-Whitney U. Secara deskriptif daya hambat ekstrak etanol biji pinang memiliki kemampuan daya hambat terhadap jamur C. albicans. Analisis statistik semua taraf konsentrasi memberikan pengaruh yang nyata dalam menghambat pertumbuhan jamur. Uji lanjut menunjukkan konsentrasi 20 g/ml dan 80 g/ml serta 60 g/ml dan 80 g/ml memiliki nilai signifikasinya <0,05, yang berarti ada perbedaan pengaruh dalam menghambat pertumbuhan jamur C. albicans. Kesimpulan penelitian ini adalah ekstrak etanol biji pinang dapat menghambat pertumbuhan jamur C. albicans.

Areca nut (Areca catechu Linn) is a plant that is widely distributed in tropical and subtropical regions. People have used it to treat various health problems. This study aims to determine the ability of betel nut ethanol extract to inhibit the growth of Staphylococcus aureus and Escherichia coli bacteria. The research method is experimental. Stages of research, first the betel nut is dried by aerating for 7-10 days. After drying, the seeds are ground into powder. The extraction stage of the active compounds uses the maceration method using 92% ethanol, evaporation is carried out using a rotary vacuum evaporator. The results of the maceration extract were carried out with phytochemical tests and bacterial inhibitory tests against E. coli, and S. aureus, carried out by the Kirby Bauer method. The detected metabolites were flavonoids, tannins and terpenoids. These metabolites have the ability as antimicrobials. The results of the inhibition test of the ethanol extract of areca nut seeds showed descriptively that the ethanol extract had a better inhibitory ability against S. aureus bacteria, compared to E. coli. The conclusion of this study is that the ethanol extract of areca nut seeds can inhibit the growth of E.coli and S.aureus.
